Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0042] The following is for reference. Figures 1-7The air conditioner 100 according to an embodiment of the present invention is described in which the ground wire 6 is fixed to the grounding plate 5, so that the ground wire 6 can connect the ground wire connection part 11 to the terminal block 4 through the grounding plate 5. In this way, the ground wire 6 can guide the leakage current of the evaporator 1 to the ground at the terminal block 4, so as to protect personal safety and equipment safety. Furthermore, the grounding plate 5 is installed on the motor cover 31, which can meet the installation requirements of the ground wire 6 and is not limited by the structure of the electrical control box 2. It can also avoid the grounding plate 5 occupying the internal and external space of the electrical control box 2, reduce the impact of the grounding plate 5 on the body length of the air conditioner 100, and facilitate the installation of the air conditioner 100.

[0043] like Figures 1-7 As shown, an air conditioner 100 according to an embodiment of the present invention includes: an evaporator 1, an electrical control box 2, an air conditioner motor, a terminal block 4, and a grounding plate 5.

[0044] The evaporator 1 is provided with a ground wire connection part 11; the electrical control box 2 and the evaporator 1 are distributed along the length of the air conditioner 100, the air conditioner motor is used to connect the air conditioner fan, and the air conditioner motor has a motor cover 31; the terminal block 4 is installed on the electrical control box 2, the grounding plate 5 is installed on the motor cover 31, the terminal block 4 and the ground wire connection part 11 are connected through the ground wire 6, and the ground wire 6 is fixed to the grounding plate 5.

[0045] Specifically, the evaporator 1 is used to realize the cooling function of the air conditioner 100. A ground wire connection part 11 is provided on the evaporator 1, through which the ground wire 6 can be connected to the evaporator 1. In the event of leakage in the evaporator 1, the leakage current is conducted to the ground, protecting personal safety and equipment safety. The electrical control box 2 is the core part of the normal operation of the air conditioning system. It is mainly responsible for the various functions of the air conditioning system and ensures that the air conditioning system operates according to the set mode and parameters. By distributing the electrical control box 2 and the evaporator 1 along the length of the air conditioner 100, the electrical control box 2 and the evaporator 1 can be separated, avoiding interference between the two, which would cause the air conditioner 100 to malfunction. It can also reduce the space occupied by the air conditioner 100 in the width and height directions, which is beneficial to the installation of the air conditioner 100.

[0046] Meanwhile, the air conditioner motor is connected to the air conditioner fan, so that the air conditioner motor can provide driving force to the air conditioner fan, drive the air conditioner fan to rotate to promote air flow, and the air conditioner motor has a motor cover 31, which is used to cover the air conditioner motor and protect the internal components of the air conditioner motor from the intrusion of external impurities, dust, moisture and other pollutants, thereby improving the reliability of the air conditioner motor.

[0047] Terminal block 4 provides a centralized electrical connection point. By installing terminal block 4 on electrical control box 2, terminal block 4 can be connected to electrical control box 2, allowing wires and cables to be connected to the circuit board of electrical control box 2, thereby realizing various functions of the air conditioning system. Grounding plate 5 provides a safe path to conduct leakage current from evaporator 1 to the ground, so as to protect personal safety and equipment safety. By installing grounding plate 5 on motor cover 31, grounding plate 5 can be connected to motor cover 31 to fix grounding plate 5, so that ground wire 6 can be connected to the ground through grounding plate 5 to conduct leakage current to the ground.

[0048] Furthermore, by connecting the terminal block 4 to the ground wire connection part 11 via the ground wire 6, the ground wire 6 connected to the evaporator 1 can be connected to the terminal block 4, thereby achieving the conduction between the ground wire 6 and the ground. This allows the leakage current of the evaporator 1 to be guided to the ground. By fixing the ground wire 6 to the grounding plate 5, the grounding plate 5 can be placed between the ground wire connection part 11 and the terminal block 4. The ground wire 6 is connected between the ground wire connection part 11 and the terminal block 4 through the grounding plate 5, so that the leakage current of the evaporator 1 can be guided along the ground wire 6 to the grounding plate 5 first, and then from the grounding plate 5 along the ground wire 6 to the terminal block 4, where it is connected to the ground.

[0049] It should be noted that installing the grounding plate 5 on the motor cover 31 can meet the installation requirements of the ground wire 6 without adding any parts, which can reduce the installation cost. At the same time, it is not limited by the structure of the electrical control box 2, and the grounding plate 5 can avoid occupying the internal and external space of the electrical control box 2. This can reduce the impact of the grounding plate 5 on the body length of the air conditioner 100, which is beneficial to the installation of the air conditioner 100.

[0050] Therefore, the evaporator 1 is used to realize the cooling function of the air conditioner 100. A terminal block 4 is installed in the electrical control box 2 so that wires and cables can be connected to the circuit board in the electrical control box 2 to realize various functions of the air conditioning system. At the same time, a ground wire connection part 11 is provided on the evaporator 1 to connect the ground wire 6. The ground wire connection part 11 is connected to the terminal block 4 through the ground wire 6, and the ground wire 6 is fixed to the grounding plate 5 so that the ground wire 6 can connect the ground wire connection part 11 to the terminal block 4 through the grounding plate 5. In this way, the ground wire 6 can conduct the leakage current of the evaporator 1 to the ground at the terminal block 4. Furthermore, the grounding plate 5 is installed on the motor cover 31 to meet the installation requirements of the ground wire 6 and to avoid the grounding plate 5 occupying the internal and external space of the electrical control box 2.

[0051] According to an embodiment of the present invention, the air conditioner 100, by fixing the ground wire 6 to the grounding plate 5, allows the ground wire 6 to connect the ground wire connection part 11 to the terminal block 4 through the grounding plate 5. This enables the ground wire 6 to guide the leakage current of the evaporator 1 to the ground at the terminal block 4, thereby protecting personal safety and equipment safety. Furthermore, installing the grounding plate 5 on the motor cover 31 can meet the installation requirements of the ground wire 6 without being limited by the structure of the electrical control box 2. It can also avoid the grounding plate 5 occupying the internal and external space of the electrical control box 2, reduce the impact of the grounding plate 5 on the body length of the air conditioner 100, and facilitate the installation of the air conditioner 100.

[0052] In some embodiments, the terminal block 4 is detachably mounted to the electrical control box 2; and / or, the grounding plate 5 is detachably mounted to the motor cover 31.

[0053] Specifically, the terminal block 4 is installed on the electrical control box 2, allowing wires and cables to be connected to the circuit board inside the electrical control box 2. The terminal block 4 is detachably installed on the electrical control box 2, making it easy to connect or disconnect the terminal block 4 from the electrical control box 2. When the terminal block 4 is connected to the electrical control box 2, the wires and cables can be connected. When the terminal block 4 is disconnected from the electrical control box 2, the terminal block 4 can be replaced, reducing later maintenance costs. The detachable connection between the terminal block 4 and the electrical control box 2 can be achieved through bolts or other connecting parts, and the connection method is simple, reliable, and easy to operate.

[0054] Furthermore, the grounding plate 5 is installed on the motor cover 31, which avoids the grounding plate 5 occupying the internal and external space of the electrical control box 2. The grounding plate 5 is detachably installed on the motor cover 31, which makes it easy to connect the grounding plate 5 to the motor cover 31 or separate the two. When the grounding plate 5 is connected to the motor cover 31, the ground wire 6 can be connected. When the grounding plate 5 is separated from the motor cover 31, the grounding plate 5 can be replaced, which can reduce the later maintenance cost. The detachable connection between the grounding plate 5 and the motor cover 31 can be achieved by bolts or other connecting parts. The connection method is simple, reliable and easy to operate.

[0055] In some embodiments, the terminal block 4 is provided with a first plug-in positioning part 41 and a first connecting part 42, and the electrical control box 2 is provided with a second plug-in positioning part 21 and a second connecting part 22; wherein, the first plug-in positioning part 41 and the second plug-in positioning part 21 are plugged in and positioned, and the first connecting part 42 and the second connecting part 22 are detachably connected through a first connector 421.

[0056] Specifically, the terminal block 4 is detachably installed on the electrical control box 2. A first insertion positioning part 41 and a first connecting part 42 are provided on the terminal block 4. The first insertion positioning part 41 is used to position the terminal block 4, and the first connecting part 42 is used to fix the terminal block 4. A second insertion positioning part 21 and a second connecting part 22 are provided on the electrical control box 2. The second insertion positioning part 21 is used to engage with the first insertion positioning part 41 to ensure the accuracy of the terminal block 4's installation position. The second connecting part 22 is connected to the first connecting part 42 via a first connector 421 to connect the terminal block 4 to the electrical control box 2. The first connecting part 42 and the second connecting part 22 are detachably connected via the first connector 421, which facilitates the connection of the terminal block 4 to the electrical control box 2 for installation, or the separation of the terminal block 4 from the electrical control box 2 for disassembly, thereby facilitating the replacement of the terminal block 4 and reducing subsequent maintenance costs.

[0057] The first insertion positioning part 41 and the second insertion positioning part 21 can be arranged facing each other to facilitate the insertion and cooperation of the first insertion positioning part 41 and the second insertion positioning part 21 to achieve the positioning of the terminal block 4. The first connecting part 42 and the second connecting part 22 can be arranged facing each other to facilitate the first connecting member 421 to pass through the first connecting part 42 and the second connecting part 22 in sequence to fix the terminal block 4. Thus, the terminal block 4 can be installed by positioning first and then connecting, which can effectively improve the reliability of the installation of the terminal block 4.

[0058] In some embodiments, the first insertion positioning part 41 and the first connecting part 42 are respectively located on the two oppositely distributed edges of the terminal block 4, and the first insertion positioning part 41 is adapted to be inserted into the second insertion positioning part 21 in a direction away from the second connecting part 22.

[0059] Specifically, the first insertion positioning part 41 is used for positioning the terminal block 4, and the first connecting part 42 is used for installing the terminal block 4. By setting the first insertion positioning part 41 and the first connecting part 42 on the opposite sides of the terminal block 4, the first insertion positioning part 41 and the first connecting part 42 can be spaced apart, so that the terminal block 4 and the electrical control box 2 can be matched from two opposite positions at the same time. This can improve the reliability of the connection between the two, and can balance the force, thereby improving the stability of the connection between the two. In addition, the first insertion positioning part 41 can be inserted into the second insertion positioning part 21 in a direction away from the second connecting part 22, that is, the first insertion positioning part 41 can be inserted into the second insertion positioning part 21 from the second connecting part 22 toward the second insertion positioning part 21, so as to realize the positioning and matching between the terminal block 4 and the electrical control box 2.

[0060] For example, such as Figure 1 , Figure 4 and Figure 5As shown, the first insertion positioning part 41 can be the edge of the terminal block 4, and the second insertion positioning part 21 can be constructed as a U-shaped groove, so that the first insertion positioning part 41 can extend into the second insertion positioning part 21 and cooperate with the second insertion positioning part 21. The length of the U-shaped groove is less than the length of the edge of the terminal block 4 to reduce the processing difficulty. Moreover, the first connector 421 can be a self-tapping screw.

[0061] In some embodiments, the grounding plate 5 is detachably connected to the motor cover 31 via at least one second connector 51.

[0062] Specifically, the grounding piece 5 is detachably installed on the motor cover 31. The grounding piece 5 can be detachably connected to the motor cover 31 through the second connector 51, which makes it easy to connect the grounding piece 5 to the motor cover 31 or separate the two. The second connector 51 is at least one, that is, the number of second connectors 51 can be one, two or three, etc. The grounding piece 5 can be connected to the motor cover 31 through at least one second connector 51. The second connector 51 can be a bolt.

[0063] In such Figure 1 , Figures 3-5 In the embodiment shown, there is only one second connector 51, which can be used to connect the grounding piece 5 to the motor cover 31. The number of second connectors 51 is not limited to that described in this embodiment and can be flexibly set according to specific needs and space.

[0064] In some embodiments, the motor cover 31 and the control box 2 are located at the same end of the evaporator 1, and the grounding plate 5 is located between the evaporator 1 and the control box 2 along the length of the air conditioner 100.

[0065] Specifically, the air conditioner motor is connected to the evaporator 1 to realize the cooling function, and the electrical control box 2 is connected to the evaporator 1 to realize functions such as temperature control and mode control. By setting the motor cover 31 and the electrical control box 2 at the same end of the evaporator 1, it is easy to connect the air conditioner motor and the electrical control box 2 to the evaporator 1 at the same time, and it can make the structure compact, reduce the space occupied by the air conditioner 100, and facilitate the installation of the air conditioner 100. In addition, the grounding plate 5 is set between the evaporator 1 and the electrical control box 2, so that the distance between the grounding plate 5 and the evaporator 1 and the electrical control box 2 is relatively close, so that the ground wire 6 can be connected between the ground wire connection part 11 and the terminal block 4 through the grounding plate 5.

[0066] In some embodiments, the two ends of the ground wire 6 are respectively connected to the terminal block 4 and the ground wire connection part 11, and the motor cover 31 is provided with a winding part 311; the middle part of the ground wire 6 is wound around the winding part 311, and both ends of the ground wire 6 are higher than the middle part of the ground wire 6.

[0067] Specifically, the ground wire 6 can be connected between the ground wire connection part 11 and the terminal block 4 through the grounding plate 5. That is, the two ends of the ground wire 6 are connected to the terminal block 4 and the ground wire connection part 11 respectively. The motor cover 31 is provided with a winding part 311 for winding. The middle part of the ground wire 6 is wound around the winding part 311, so that the winding part 311 can limit the ground wire 6 and allow the ground wire 6 to extend in a set direction, so as to prevent the ground wire 6 from being tangled inside the air conditioner 100. The middle part of the ground wire 6 can be bent at a certain arc at the winding part 311, so that both ends of the ground wire 6 are higher than the middle part of the ground wire 6. That is, the middle part of the ground wire 6 is the lowest point of the ground wire 6, which is lower than the connection between the ground wire 6 and the ground wire connection part 11 and the terminal block 4. This prevents water droplets dripping from the evaporator 1 from being introduced into the electrical control box 2 along the ground wire 6, causing a short circuit or fire.

[0068] For example, such as Figure 7 As shown, a wire outlet 43 can be provided on the side of the terminal block 4 facing the grounding plate 5, so that the ground wire 6 can extend from here to connect with the grounding plate 5. The edge of the wire outlet 43 can be made smooth to avoid scratching the ground wire 6. Moreover, the size of the wire outlet 43 should not be too large to reduce the possibility of water droplets entering the electrical control box 2.

[0069] In some embodiments, the winding portion 311 is located below the grounding piece 5, and the winding portion 311 has a winding opening 3111. The winding opening 3111 is configured to be open downwards and is open on both sides in the horizontal direction. The ground wire 6 is wound around the winding opening 3111.

[0070] Specifically, by placing the winding portion 311 below the grounding plate 5, the winding portion 311 can be positioned between the evaporator 1 and the electrical control box 2, preventing water droplets dripping from the evaporator 1 from being guided along the ground wire 6 to the grounding plate 5. The winding portion 311 has a winding opening 3111, and the ground wire 6 is wound around the winding opening 3111, thus achieving a connection between the ground wire 6 and the winding portion 311. This allows the winding portion 311 to restrict the extension direction of the ground wire 6. Furthermore, the winding opening 3111 is designed to open downwards to facilitate the routing of the ground wire 6 from... The lower end of the winding port 3111 extends into the winding port 3111, which can make the winding part 311 arc-shaped to restrict the extension direction of the ground wire 6. At the same time, the winding port 3111 passes through both sides in the horizontal direction, so that the side of the winding part 311 facing the evaporator 1 and the side facing the electrical control box 2 can be connected through the winding port 3111. This allows the ground wire 6 to pass through the winding port 3111 and connect to the ground wire connection part 11 and the terminal block 4 respectively, so that the leakage current of the evaporator 1 is guided to the ground at the terminal block 4, protecting personal safety and equipment safety.

[0071] In some embodiments, the motor cover 31 is provided with a first water-blocking portion 32, which is located above the grounding plate 5 and extends protruding away from the motor cover 31 to shield the grounding plate 5.

[0072] Specifically, the first water-blocking part 32 is used to shield the grounding plate 5. The first water-blocking part 32 is positioned above the grounding plate 5 so that it can prevent water droplets from the evaporator 1 from falling onto the grounding plate 5, thereby improving the reliability of the grounding plate 5. Furthermore, the first water-blocking part 32 is positioned on the motor cover 31 and extends protruding away from the motor cover 31, so that the first water-blocking part 32 has a certain length, thereby increasing the area that the first water-blocking part 32 can shield the grounding plate 5, and thus effectively improving the reliability of the first water-blocking part 32 in shielding the grounding plate 5.

[0073] It should be noted that the first water-blocking part 32 can be constructed as a flat plate and extended upward at an angle to further improve the reliability of the first water-blocking part 32 in shielding the grounding piece 5.

[0074] In some embodiments, the motor cover 31 is provided with a second water-blocking portion 33, which is located above the grounding plate 5 and close to the side of the electrical control box 2. At least a portion of the ground wire 6 is configured to be led along the second water-blocking portion 33 to the grounding plate 5, and the second water-blocking portion 33 blocks at least a portion of the ground wire 6 on the side facing the evaporator 1.

[0075] Specifically, the second water-blocking part 33 is used to shield at least a portion of the ground wire 6. The second water-blocking part 33 is disposed above the grounding plate 5 and close to the side of the electrical control box 2. The at least portion of the ground wire 6 is arranged to lead along the second water-blocking part 33 to the grounding plate 5. This makes the at least portion of the ground wire 6 have the same extension direction as the second water-blocking part 33, which increases the reliability of the second water-blocking part 33 shielding at least a portion of the ground wire 6. Furthermore, by shielding the at least portion of the ground wire 6 on the side facing the evaporator 1, the second water-blocking part 33 is disposed between the evaporator 1 and at least a portion of the ground wire 6, which effectively prevents water droplets dripping from the evaporator 1 from splashing onto the ground wire 6 and being introduced into the electrical control box 2, causing a short circuit or fire.

[0076] Furthermore, it should be noted that the second water-blocking part 33 can be extended outward from the motor cover 31 to increase the area of ​​the second water-blocking part 33 and improve the reliability of the operation of the second water-blocking part 33. In addition, the first water-blocking part 32 can be connected to the second water-blocking part 33 to further improve the reliability of the first water-blocking part 32 and the second water-blocking part 33 in blocking water droplets dripping from the evaporator 1.

[0077] In some embodiments, the air conditioner wall unit 100 further includes an air conditioner frame 7, the evaporator 1, the electrical control box 2 and the air conditioner motor are all installed on the inner side of the air conditioner frame 7, the air conditioner frame 7 has a first operation port 71 and a second operation port 72, the first operation port 71 is distributed opposite to the terminal block 4, and the second operation port 72 is distributed opposite to the grounding plate 5.

[0078] Specifically, the air conditioner frame 7 is used to shield the components inside the air conditioner unit 100. The evaporator 1, the electrical control box 2, and the air conditioner motor are all installed inside the air conditioner frame 7. This protects the evaporator 1, the electrical control box 2, and the air conditioner motor from external impurities, dust, moisture, and other contaminants, thereby improving the reliability of the evaporator 1, the electrical control box 2, and the air conditioner motor. The air conditioner frame 7 has a first operating port 71 and a second operating port 72. Both the first operating port 71 and the second operating port 72 provide a position for maintenance personnel to operate, ensuring sufficient visibility and convenient operation. The first operating port 71 is directly opposite the terminal block 4, allowing maintenance personnel to extend fixing tools from the first operating port 71 to the terminal block 4 to connect wires or cables. At the same time, the second operating port 72 is directly opposite the grounding plate 5, allowing maintenance personnel to extend fixing tools from the second operating port 72 to the grounding plate 5 to fix the ground wire 6.

[0079] It should be noted that the edge of the second operating port 72 can be folded to avoid the position of the second connector 51, and the grounding plate 5 can be installed on the motor cover 31. This can increase the distance between the grounding plate 5 and the terminal block 4, thereby increasing the routing distance of the ground wire 6. This can fully consume the excess wire, so that the ground wire 6 does not need to be bent sharply to be stuffed inside the terminal block 4. This can better manage the wires and improve the ease of assembly.

[0080] In some embodiments, the first operation port 71 is connected to the second operation port 72.

[0081] Specifically, the first operating port 71 is directly opposite the terminal block 4, and the second operating port 72 is directly opposite the grounding plate 5. The ground wire 6 connects the ground wire connection part 11 to the terminal block 4 through the grounding plate 5. That is, the ground wire 6 can connect the grounding plate 5 to the terminal block 4. The first operating port 71 and the second operating port 72 are connected so that the ground wire 6 can extend from the terminal block 4 to the grounding plate 5 to connect with the grounding plate 5, thereby realizing the connection of the ground wire 6 between the evaporator 1 and the terminal block 4.

[0082] In some embodiments, the terminal block 4 is connected to a connecting wire 9 and / or a power cord 10.

[0083] In other words, the terminal block 4 is connected to the connecting wire 9 or the power line 10, or the terminal block 4 is connected to both the connecting wire 9 and the power line 10. Thus, when the ground wire 6 is connected to the terminal block 4, the ground wire 6 can be connected to the connecting wire 9 and / or the power line 10, thereby connecting the ground wire 6 to the ground. In the event of leakage in the evaporator 1, the leakage current of the evaporator 1 can be directed to the ground, protecting personal safety and equipment safety.

[0084] In some embodiments, the air conditioner wall unit 100 further includes a wire clamp 8, which is detachably connected to the electrical control box 2 and is used to secure the connecting wire 9 and / or the power cord 10.

[0085] Specifically, the wire clamp 8 is used to fix the connecting wire 9 or the power cord 10, or to fix the connecting wire 9 and the power cord 10 simultaneously, so as to prevent the connecting wire 9 and / or the power cord 10 from shaking and reducing the reliability of the connection with the terminal block 4. The wire clamp 8 can be detachably connected to the electrical control box 2 by bolts or other connecting parts, so as to facilitate connecting the wire clamp 8 to the electrical control box 2 or separating the two. When the wire clamp 8 is connected to the electrical control box 2, the wire clamp 8 can be fixed, improving the reliability of the wire clamp 8. When the wire clamp 8 is separated from the electrical control box 2, the connecting wire 9 and / or the power cord 10 can be fixed.

[0086] In such Figure 4 In the embodiment shown, the terminal block 4 is connected to both the connecting wire 9 and the power wire 10. When the ground wire 6 is connected to the terminal block 4, the ground wire 6 can be connected to both the connecting wire 9 and the power wire 10 simultaneously, which can effectively connect the ground wire 6 to the ground, improve the reliability of guiding the leakage current of the evaporator 1 to the ground, and the connecting wire 9 and the power wire 10 can be fixed at the same time by the wire clamp 8, which can reduce the number of wire clamps 8 and reduce the installation cost.

[0087] Additionally, a wire-passing hole can be provided in the wire clamp 8 to pass the connecting wire 9 and the power wire 10 through the wire-passing hole, which can prevent the wire clamp 8 from squeezing the connecting wire 9 and the power wire 10 and causing damage to the connecting wire 9 and the power wire 10.

[0088] In some embodiments, the ground wire 6 is detachably fixed to the grounding plate 5 via a third connector 52.

[0089] Specifically, the ground wire 6 is fixed to the grounding plate 5. The ground wire 6 can be detachably fixed to the grounding plate 5 through the third connector 52. That is, the ground wire 6 can be connected to the grounding plate 5 or separated from the grounding plate 5 through the third connector 52. When the ground wire 6 is connected to the grounding plate 5, the ground wire 6 can be connected between the evaporator 1 and the terminal block 4. When the ground wire 6 is separated from the grounding plate 5, the evaporator 1 can be disconnected from the terminal block 4 to facilitate the replacement of the grounding plate 5. The third connector 52 can be a grounding screw.

[0090] For example, such as Figure 2 and Figure 6As shown, a grounding hole 53 can be provided on the grounding plate 5, and the third connector 52 can be passed through the grounding hole 53 to fix the ground wire 6. A clearance groove 312 can be provided on the motor cover 31 at the position directly opposite to the grounding hole 53 to avoid the third connector 52 and ensure the reliable connection of the third connector 52. The clearance groove 312 can be constructed as a cylindrical groove to adapt to the assembly requirements of the grounding plate 5.

[0091] Therefore, when maintenance personnel are wiring, they can first fix the connecting wire 9 and the power wire 10 to the electrical control box 2 at the first operating port 71 using the wire clamp 8, and then connect the connecting wire 9 and the power wire 10 to the terminal block 4. The ground wire 6 can pass through the outlet 43 and extend along the second water baffle 33, and be fixed to the grounding plate 5 by the grounding screw. The fixing tool can be inserted into the machine body through the first operating port 71 to fix the grounding screw.
